Second, ANOVAs performed on male and female fitness returned highly significant differences between hemiclones across laboratories, but no hemiclone‐by‐laboratory effects (females: hemiclone—F 8,45 = 11.42, P < 0.0001, hemiclone‐by‐laboratory—F 8,45 = 1.19, P = 0.33; males: hemiclone—F 8,63 = 11.34, P < 0.0001, hemiclone‐by‐laboratory—F 8,45 = 1.54, P = 0.16; laboratory term nonsignificant in both analyses, as expected for Z‐transformed fitness data).
